Black labs are part of a larger group of dogs called Labrador Retrievers, which are originally from Newfoundland. These dogs are popular and make good dogs for active families. An average lifespan for the black lab is 10 to 12 years. Some factors play a large role in determining how long the animal lives, including common diseases and issues among black labs.

According to PetMD, common health conditions among labs include patellar luxation, osteochondritis dissecans, or canine elbow and shoulder dysplasia, and canine hip dysplasia. Other health problems might occur as well, such as diabetes, muscular dystrophy, exercise-induced collapse and tricuspid valve dysplasia. Minor health concerns include hypothyroidism, cataracts and retinal dysplasia.
